Described first straight wall and electric power trench bottom delivery position offer multiple installing hole.
Outer baffle integrated with housing it is provided with outside described first straight wall.
Being provided with outer baffle outside described first straight wall, described outer baffle glueds joint with housing.
Compared with prior art, it is an advantage of the current invention that:
The shield for mining under railways of the present invention, including the housing of the band inner chamber using composite to make, housing cavity is filled out
Being filled with foam, case top interval forms the first straight wall, the second straight wall and connection wall, shape between the first straight wall and the second straight wall
Become electric power groove, between the second straight wall and connection wall, form signal of communication groove.In this structure, housing uses composite to make and shape
Becoming inner-cavity structure, its lumen loading has foam, and it has corrosion resistance, extends the service life of this shield；Its molding is easy,
Improve production efficiency；It is lightweight, is on the one hand easily installed and transports, and on the other hand reduces the burden of bridge itself.
